## Homework Statement

A body of mass 5 kg is initially at rest. At time t=0, a constantly increasing force is applied to the body for 7.5 seconds according to:F(t)=at; where a is a constant 0.866 N/s. Determine the distance x the body travels during the application of the force.

## Homework Equations

delta E of system = sigma T

sum of forces in y direction =0

normal force - mass*gravitational acceleration=0

work=force*change in position

1/2mass*final velocity^2 = 1/2mass*initial velocity^2 + work

## The Attempt at a Solution

At kind of a loss for where to start this problem because the force is not constant.

Can I some how find a value for Work and use that to solve for final velocity and use that to find change in position? Please Help!
